摘要
【目的】选育适合设施与露地兼用型西瓜新品种,丰富广西优质无籽西瓜品种类型,为广西西瓜产业高质量发展提供品种支持。【方法】以四倍体西瓜"MT410n-1"为母本,以"W-8"为父本,配组选育三倍体无籽西瓜一代杂交种,并进行多茬新组合栽培观察及综合鉴定评价和同步进行多点、多造大棚设施环境栽培与露地环境栽培的品种比较试验、区域试验、生产试验。【结果】配组选育出三倍体无籽西瓜一代杂交种"桂系4号",其全生育期春茬85~110d,具有抗病抗逆性强,不易早衰,品相和品质极好,且耐贮运;一般单瓜质量2.4~5.0kg,大棚栽培产量2500~3400 kg/667m^2,露地栽培产量2000~2500 kg/667m^2。【结论】无籽西瓜新品种"桂系4号"适宜大棚设施栽培和露地栽培,可作精品西瓜生产,种植效益高,可在西瓜种植地区推广种植。
【Objective】Breeding of a new watermelon variety for both facility and open-field cultivation in order to enrich the varieties of high-quality seedless watermelon,and provide variety support for the highquality development of watermelon industry in Guangxi.【Method】The first generation hybrid of triploid seedless watermelon,“Guixi NO.4”was selected,used the tetraploid watermelon“MT410n-1”as the fe⁃male parent and“W-8”as the male parent.The observation and comprehensive evaluation of the new cross combination have been carried out continuously,the multi point comparative test,regional test and production test have been carried out simultaneously in facilities and open-field.【Result】The first gener⁃ation hybrid of triploid seedless watermelon,“Guixi NO.4”was breeding.The total growing period is 85~110 days.The plant grows vigorously with strong disease resistance and adverse resistance.The fruit is round,the skin is dark green with concealed stripe and good luster.The peel is moderately hard and the cortex leathery with advantage of good storage and transportation.The single fruit weight is 2.5~5.0kg,yield 2500~3400kg/667m^2 in facility and 2000~2500kg/667m2 in open space.【Conclusion】“Guixi NO.4”can be popularized as the high-quality watermelon with high planting benefit in the area which is suitable for planting watermelon.
